Hi Dougals:
Galdos is *currently *integrating real time traffic data, geographic
features, incident reports using OGC standards - namely GML
(observations, value objects for sensor data, features/geometry for the
road network, sensor locations) - WFS for automated propagation and
uptdate of this information and WMS/FPS (Feature Portrayal Service) for
real time integration of these elements into congestion maps etc. This
is real open standards plug and play on a wide area network. OGC
standards work.
Sincerely,
Ron
